2 A 7-sheet Survey Questionnaire Resource Inputs and Basic Headings Outline Overall Validation Process Timetable Overall Methodology Data Requirements 2

3 Classification of the Construction Sector Construction and Civil Engineering 3 3 Basic Headings 3 Categories of Input Resources 50 Input Resources Residential Building Civil Engineering Non- Residential Building Machinery Equipment Labor Materials & Products Equipment items Labour services Machinery Equipment Labor Materials & Products Equipment items Labour services Machinery Equipment Labor Materials & Products Equipment items Labour services

4 To be obtained from National Accounts as part of the process of splitting GDP into basic headings Data Requirements Materials Equipment Labour Residential Non Residential Civil Engineer.

5 Calculate unweighted PPPs for the 3 sub-headings by group of countries Basic Heading (BH) breakdown into 3 sub-headings: Materials, Labor, Equipment Aggregate the PPPs for the 3 subheadings using the Resource Mixes to obtain weighted PPPs for the 3 BHs Combine the adjusted BH PPPs using expenditures on the BHs as weights to obtain overall PPPs for construction Adjust the 3 BH PPPs for mark ups, professional fees and end-user taxes Overall Methodology 5

6 Material Introduction A 7-Sheet Survey Questionnaire Equipment Labour Project Prices (Optional – used as checks on input based PPPs) Explanatory Notes Supporting Information 5 Technical Survey Forms Identification Form 7 6

7 Country collect mid year national average prices 1 Currency 2 Survey respondent Name 3 Employer 4 Type of Employer 5 ConsultantacademicresearchGovern.tOther Contact details 6 Telephone 7 8 Purpose of the survey Base date for prices Please tick box 9 Prices averaged over the yearMid year prices National average price level Geographical base 10 National average factor Introduction 7

8 General notes Identify 1 Locally available Commonly used Identical or equivalent to prescribed items Materials and services and collect their prices Item descriptions and units Not identical but equivalent Proprietary products Not metric dimensions For materials & equipment For labour Other notes (materials, equipment, labour) If products specs. Columns 10 If alternative units of measure. Column 5 Column 4 Columns 10, 8 or 7 Report in For equipment hire, if per day or week If unit not per hour Report For labor, if different unit Situation Number of hours In Column 5 In Column 8 In Column 4 Column 5 2. Notes – Item Descriptions 8

9 Types of prices Geographical location Local resource and distribution costs, geographic, seismic or climatic conditions, local market conditions, etc. 2. Notes - Prices Labour Actual employment cost Equipment hire Rental charges Materials Actual purchasers prices Site context Respondents should assume reasonable site contexts with good access. Size of projects The larger the projects, the larger the quantities, and hence lower unit costs. Prices can be influenced 9

10 3. Material – Layout of the questionnaire Ref Item Specifications Notes Pref. Unit Alternati ve. Unit Unit Price Residential Non Residential Civil Engineering Notes and Comments 01 Aggregat e for concrete Clean, hard, strong m Electriv ity Typical average commercial..

11 4. Equipment – Layout of the questionnaire Ref Item Specifications Notes Pref. Unit Alternative. Unit Unit Price with operator Unit Price without operator Notes and comments 01 Wheeled loader and excavator 1.0m3 loader capacity hour Compact track loader Rated capacity: 864 kg hour Comments 11

12 5. Labour – Layout of the questionnaire Ref Item Pref. Unit Alternative. Unit Number of hours Unit Price Notes and comments 01 General (unskilled) labourers hour Structural steel worker hour Comments 06 Electrician hour 07 Machine (equipment) operator hour 12

13 6. Project Prices – Layout of the questionnaire The collection of project prices is optional as those prices are not essential for the calculation of PPPs. They can however be used as an additional resource in the validation process. Ref Project Type Pref. Unit Alternative. Unit Notes and comments 01 Single storey average quality detached house masonry (brick or block) or timber frame m 2 floor area 02 Two storey attached house, mass market, centre unit in terrace/ row of four units, otherwise as above m 2 floor area Length of concrete sewer pipes, 0.5m diameter, average 2 m depth m length 11 Length of concrete sewer pipes, 1m diameter, average 3 m depth m length Unit rate m 2 floor area 5 m length 13
